IMPROVEMENT lN MACHINES FOR SCREWING THE UPPERS ONTO THE SOLES AND HEELS 0F BOOTS, &c.

Specification forming part of Letters Patent No. 149,008, datcd March 21, 187-1; application filed September 23, 1873.

To all whom it may concern:

Be it known that I, GHARLEs TYSON, of the city and county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Machines for Screwing the Uppers onto the Soles and Heels of Boots and Shoes, of which the following is a specification:

This invention relates to the patented machine of Amasa B. Howe, assignee of Eugene Lemercier, administrator of Louis Jules Sellier, of date December 16, 1862, for screwing the uppers onto the soles and heels of boots and shoes, and for uniting other articles, and in which the screwing-mandrel is operated by a hand-crank and suitable connecting cog-gearing, to thread the wire, and to screw it home and clinch it to the upper. The working of such machines is not only laborious, but necessarily slow, the work being held by one hand, while with the other the operator turns the crank to form and enter the screw into the WOIk. It is the object of the improvement embraced in this patent to overcome this objection and disadvantage; and it consists of a stopping and starting hand-lever, in combination with fast and loose friction driving-pulleys, and the screwing-spindle having a pulley connecting by band with the loose friction-pulley, whereby the screwing-spindle is driven by steam-power, and stopped and started, and driven slow or fast, at the will of the operator by means of the lever, and during any part of the screwing operation; the advantages and benefits resulting from my said improvement being the relief of the operator from constant and heavy labor, and the production of more than double the number of boots or shoes, the hand machine turning out about forty pairs in a day, while, by the simple attachment of the controlling-lever with steam-power, the operator can make from eighty to ninety pairs daily, which is a matter of the highest advantage and economy in the manufacture of boots and shoes.

In the accompanying drawing, Figure 1 represents a side view of a machine with my improvement applied thereto, and Fig. 2 is a top view thereof,

The machine shown is in all respects, except in the particulars of my improvements, the same as described and shown in the patent referred to, and need not, therefore, be particularly described in this patent, further than to state that the mandrel A has a revolving and axial movement, and carries the wire 0, upon which the screw is cut by a chaser, in a continuous manner, and, while being so out, is screwed into the material to be united and riveted at its inner end, and immediately thereafter the wire is cut from the inserted screw by a knife carried by the nose, the material being supported upon an iron surface or beak- -iron, L, during the operation, and which metallic beak-support L effects the clinching of the screw when screwed home; while the work is held fast by means of a pressing-nose, D, which can be elevated and depressed as required in relation to the metallic support, as in passing from the heel to the shank of the shoe; and the axial movement of the spindle is efiected by the bisected nut Z.

My improvement refers only to the manner of driving and controlling the operation of the spindle A, which carries the wire a for the screws. This spindle passes through a pulley, B, mounted within a forked bracket, (3, of the nose-carrier D, and, while the mandrel is revolved by the pulley, yet, by a groove and feather, it is free to be moved vertically through said pulley, to effect the proper'feed in cutting the screwthread upon the wire, screwing it into the sole, and clinching its inner end. horizontal shaft, E, is mounted in suitable bearings at the rear of the frame, and driven by steam or other power. Upon this shaft is fitted a fast and loose friction-pulley, F and G, andv a band, H, connects the loose pulley G with the mandrel-pulley B. The contiguous ends of the fast and loose pulleys, one or both, are faced with leather or rubber c, so that when brought together both will be revolved, and for this purpose the loose pulley G is capable of being moved upon its shaft E toward and from the fast pulley F, to bring it into or out of contact with the fast 'pulley by means of a hand-lever, I, pivoted back of the driving-shaft at J, and, extending forward, rests upon an arm, (I, in convenient reach of the operator. This lever I carries a horizontal pressing-roller, K, arranged to bear against the outside end of the loose pulley G, which, when pressed upon by forcing the free end 1 of the lever I toward the mandrel, as shown by the arrow, causes the friction at c to revolve the loose pulley G at the speed of the fast pulley, or less, at the pleasure of the operator. By this arrangement the screwing-mandrel can be revolved fast or slow, and controlled at pleasure, without regard to the driving-shaft, by the degree of pressure put upon the lever, so as to make the fast. pulley the driver for the loose pulley. The beak-iron L for supporting the work is made removable from the base M, and when so removed an iron post, L is inserted in the socket U, for use in working the soles and heels of boots and shoes, and inwhich the screws are made from a continuous wire, a stopping and starting hand-lever, I,

with its pressing-roller K, in combination with the fast and loose friction-pulleys F G and the screwing-spindle A, having a pulley, B, for imparting to it the screwing movement, as described, and to obtain the advantages stated.

In testimony whereof I have hereunto set my hand this 23d day of August, A. D. 1873.

CHARLES TYSON.
